Advertisements Been losing many SDV channels but NOT all. Reset T.A. fixes but for hours to days. Cox (in Phoenix) said I have low signal & they sent tech out & after 2 visits, got amplifier which fixed low signal. Did NOT fix the T.A. Channel loss issue! I went to a Cox Solutions Store & replaced my T.A. & All 75 Ohm Coax cables, USB cable & splitter 9-12-2016 & later replaced the POE filter 9-24-2016. (They had forgotten to give me a new filter 1st visit) No help. 9-24-16 I lost: 1341 1364 1365 1377 1387 1388 1389 But, still had: 1025 1101 1102 1362 1366 1385 All above listed channels are SDV channels which will not work at all w/o T.A. I dont want to restart T.A. every day! Note: I did NOT change out the power supply for the T.A. It is a pain to route the thin wire. Maybe I should do this? Does it make sense that the power supply can be responsible for loss of some SDV channels but not other SDV channels?
